Distributed Config System
Design a centralized configuration system with watch-based push updates, versioning and rollback, feature flags, and consistency trade-offs across etcd, Consul, and ZooKeeper.
What You Will Learn
Map the control plane and data plane boundaries behind Distributed Config System.
Reason about latency, retries, health signals, and failure isolation at service edges.
Choose where policy lives: clients, sidecars, gateways, registries, or centralized controllers.
Balance operational simplicity against flexibility, security, and multi-region behavior.
Key Decisions
Where should Distributed Config System sit in the request path or service control plane?
Which state must be strongly consistent, and which state can tolerate eventual propagation?
How do you observe health, policy drift, and partial failure without creating new bottlenecks?
What changes when the platform expands to multi-region or multi-tenant operation?
